Many compounds are psychophysically complex because they stimulate all three chemical senses; smell, taste, and irritance.3 Interrelations among these three modalities are reported over the near-threshold range, and comparisons are made for three such compounds; methanol, ethanol, and propanol. Eighteen Ss were tested over 16 sessions each under a range of conditions: a combined task condition that approximated normal drinking, in which thresholds for all three modalities were determined simultaneously, and three conditions, in each of which only one threshold in one modality was determined. Pooled results over Ss gave significant shifts in olfactory thresholds between conditions, whereas changes in gustatory and irritant acuity were less marked. Individual results yielded significant correlations between psychophysical behavior and personality measures. Factor analysis of Ss indicated the existence of subgroups of Ss, each typified by different patterns of relative sensitivity over modalities and over alcohols.  相似文献

662 former secondary school leavers of academic potential were identified for a program designed to give selected dropouts a chance to enter the University of Toledo. Following responses to questionnaires, 94 students were selected for further screening, which resulted in the final selection of 50 candidates. 34 members of the experimental group attended pre-school workshops in reading, writing, and study habit skills. 31 enrolled as regularly admitted students in academic programs of the university for the academic year. 11 completed their freshman year, although only 4 were making satisfactory academic progress.  相似文献

Conflicting predictions of reinforcement and neophobia-arousal theories were evaluated in a simple choice task. Four groups of C57BL/6J mice were administered daily two-trial tests in a uniform T-maze for 10 consecutive days. For three groups, the contingencies of footshock treatments were manipulated to reinforce alternation, perseveration, or both. A control group that was not administered footshock alternated, but all three groups that were stressed perseverated more and more across tests, despite the differences in reinforcement contingencies. These results are inconsistent with the predictions of reinforcement theory but consistent with the view that stressed or aroused animals are neophobic and use nonassociative learning (habituation) to distinguish between novel and familiar alternatives.  相似文献

Recent narrative reviews (e.g., Hom, Mitchell, Lee, and Griffeth, 2012; Hom, Lee, Shaw, and Hausknecht, 2017) advise that it is timely to assess the progress made in research on voluntary employee turnover so as to guide future work. To provide this assessment, we employed a three‐step approach. First, we conducted a comprehensive meta‐analysis of turnover predictors, updating existing effect sizes and examining multiple new antecedents. Second, guided by theory, we developed and tested a set of substantive moderators, considering factors that might exacerbate or mitigate zero‐order meta‐analytic effects. Third, we examined the holistic pattern of results in order to highlight the most pressing needs for future turnover research. The results of Step 1 reveal multiple newer predictors and updated effect sizes of more traditional predictors, which have received substantially greater study. The results of Step 2 provide insight into the context‐dependent nature of many antecedent–turnover relationships. In Step 3, our discussion takes a bird's‐eye view of the turnover “forest” and considers the theoretical and practical implications of the results. We offer several research recommendations that break from the traditional turnover paradigm, as a means of guiding future study.  相似文献

Background and objectives: This study evaluates the process and consequence of inducing self-compassion during recovery from social performance stressors. Though interest in self-compassion as an intervention target is growing, extant findings suggest that initially cultivating self-compassion can be challenging for those with high self-criticism and anxiety, common features of social anxiety disorder (SAD).

Design: Quasi-experimental design.

Methods: The current study evaluates the feasibility, content, and outcomes of a brief written self-compassion induction administered after consecutive laboratory social stressors, among adults with SAD (n?=?21) relative to healthy controls (HC; n?=?35).

Results: Findings demonstrate the feasibility of employing a written self-compassion induction among adults with (and without) SAD, reveal group differences in written responses to the induction, and suggest that the SAD group benefitted more from the induction than the HC group, based on greater reductions in state anxiety and greater increases in self-compassion during stressor recovery. Greater use of negative affect words within written responses to the self-compassion induction, but not during general writing, predicted lower subsequent state anxiety across groups, by a medium effect size.

Conclusions: Collectively, the findings support the feasibility and utility of cultivating self-compassion among adults with SAD.  相似文献

A father’s presence in the family is important for promoting adaptive behavioral functioning in children. It is unknown however, if there is a critical time during infancy and childhood for such paternal presence and involvement to affect behaviour. Using data from the Auckland Birthweight Collaborative (ABC) study, we examined the amount of paternal presence children experienced through their first 11 years of life (measured as fathers’ time spent in the same household as their children) and its effect on their behavioral outcomes at 11 years of age. After controlling for potential confounds, children who whose fathers were minimally present (left between 0 and 3.5 years of age) were twice as likely to report clinically significant behavioural difficulties as those whose fathers were present throughout childhood. Those whose fathers were present for early childhood (left between 3.5 and 7 years of age) exhibited no significant differences in their behaviour at 11 years of age when compared to their peers whose fathers remained present. Mothers reported no significant changes in their children’s behavior. Findings suggested that paternal presence early in a child’s life might be most important with regard to promoting adaptive behavioural functioning as they age.  相似文献

In the Forensic Therapeutic Outpatient department in Berlin a total of n?=?20 individually justified, therapeutically accompanied withdrawals from antiandrogenic treatment have been implemented. The sample was compared with n?=?20 patients under antiandrogenic treatment. Patients with withdrawal have been significantly older, than patients without withdrawal. No differences were found regarding their duration of further imprisonment and standardized risk-assessment (HCR-20, LSI-R, Static-99, Stable-2007, PCL-R). Firsts results of the monitoring of the withdrawals indicate, that the symptom-checklist SCL-90-R is not appropriate for that purpose. However, post-hoc both known sexual reoffendings could be identified by the Massachusetts General Hospital Sexual Functioning Questionnaire. By means of practical experience results are getting discussed.  相似文献
